-The buildpack will detect your app as Python if it has the file `requirements.txt` in the root. It will detect your app as Python/Django if there is an additional `settings.py` in a project subdirectory.
+You can also add it to upcoming builds of an existing application:
 
-It will use virtualenv and pip to install your dependencies, vendoring a copy of the Python runtime into your slug.  The `bin/`, `include/` and `lib/` directories will be cached between builds to allow for faster pip install time.
+    $ heroku config:add BUILDPACK_URL=git://github.com/heroku/heroku-buildpack-python.git
 
-Hacking
--------
+The buildpack will detect your app as Python if it has the file `requirements.txt` in the root.
 
-To use this buildpack, fork it on Github.  Push up changes to your fork, then create a test app with `--buildpack <your-github-url>` and push to it.
+It will use Pip to install your dependencies, vendoring a copy of the Python runtime into your slug.
 
-To change the vendored virtualenv, unpack the desired version to the `src/` folder, and update the virtualenv() function in `bin/compile` to prepend the virtualenv module directory to the path. The virtualenv release vendors its own versions of pip and setuptools.
+Specify a Runtime
+-----------------
+
+You can also provide arbitrary releases Python with a `runtime.txt` file.
+
+    $ cat runtime.txt
+    python-3.3.3
+
+Runtime options include:
+
+- python-2.7.6
+- python-3.3.3
+- pypy-1.9 (experimental)
+
+Other [unsupported runtimes](https://github.com/kennethreitz/python-versions/tree/master/formula) are available as well.

vendor/pip-1.5.4/CHANGES.txt

+**1.5.4 (2014-02-21)**
+
+
+* Correct deprecation warning for ``pip install --build`` to only notify when
+  the `--build` value is different than the default.
+
+
+**1.5.3 (2014-02-20)**
+
+
+* **DEPRECATION** ``pip install --build`` and ``pip install --no-clean`` are now
+  deprecated.  See Issue #906 for discussion.
+
+* Fixed #1112. Couldn't download directly from wheel paths/urls, and when wheel
+  downloads did occur using requirement specifiers, dependencies weren't
+  downloaded (PR #1527)
+
+* Fixed #1320. ``pip wheel`` was not downloading wheels that already existed (PR
+  #1524)
+
+* Fixed #1111. ``pip install --download`` was failing using local
+  ``--find-links`` (PR #1524)
+
+* Workaround for Python bug http://bugs.python.org/issue20053 (PR #1544)
+
+* Don't pass a unicode __file__ to setup.py on Python 2.x (PR #1583)
+
+* Verify that the Wheel version is compatible with this pip (PR #1569)
+
+
+**1.5.2 (2014-01-26)**
+
+
+* Upgraded the vendored ``pkg_resources`` and ``_markerlib`` to setuptools 2.1.
+
+* Fixed an error that prevented accessing PyPI when pyopenssl, ndg-httpsclient,
+  and pyasn1 are installed
+
+* Fixed an issue that caused trailing comments to be incorrectly included as
+  part of the URL in a requirements file
+
+
+**1.5.1 (2014-01-20)**
+
+
+* pip now only requires setuptools (any setuptools, not a certain version) when
+  installing distributions from src (i.e. not from wheel). (Pull #1434).
+
+* `get-pip.py` now installs setuptools, when it's not already installed (Pull
+  #1475)
+
+* Don't decode downloaded files that have a ``Content-Encoding`` header. (Pull
+  #1435)
+
+* Fix to correctly parse wheel filenames with single digit versions. (Pull
+  #1445)
+
+* If `--allow-unverified` is used assume it also means `--allow-external`. (Pull
+  #1457)
+
+
+**1.5 (2014-01-01)**
+
+
+* **BACKWARD INCOMPATIBLE** pip no longer supports the ``--use-mirrors``,
+  ``-M``, and ``--mirrors`` flags. The mirroring support has been removed. In
+  order to use a mirror specify it as the primary index with ``-i`` or
+  ``--index-url``, or as an additional index with ``--extra-index-url``. (Pull #1098, CVE-2013-5123)
+
+* **BACKWARD INCOMPATIBLE** pip no longer will scrape insecure external urls by
+  default nor will it install externally hosted files by default. Users may opt
+  into installing externally hosted or insecure files or urls using
+  ``--allow-external PROJECT`` and ``--allow-unverified PROJECT``. (Pull #1055)
+
+* **BACKWARD INCOMPATIBLE** pip no longer respects dependency links by default.
+  Users may opt into respecting them again using ``--process-dependency-links``.
+
+* **DEPRECATION** ``pip install --no-install`` and ``pip install
+  --no-download`` are now formally deprecated.  See Issue #906 for discussion on
+  possible alternatives, or lack thereof, in future releases.
+
+* **DEPRECATION** ``pip zip`` and ``pip unzip`` are now formally deprecated.
+
+* pip will now install Mac OSX platform wheels from PyPI. (Pull #1278)
+
+* pip now generates the appropriate platform-specific console scripts when
+  installing wheels. (Pull #1251)
+
+* Pip now confirms a wheel is supported when installing directly from a path or
+  url. (Pull #1315)
+
+* Fixed #1097, ``--ignore-installed`` now behaves again as designed, after it was
+  unintentionally broke in v0.8.3 when fixing Issue #14 (Pull #1352).
+
+* Fixed a bug where global scripts were being removed when uninstalling --user
+  installed packages (Pull #1353).
+
+* Fixed #1163, --user wasn't being respected when installing scripts from wheels (Pull #1176).
+
+* Fixed #1150, we now assume '_' means '-' in versions from wheel filenames (Pull #1158).
+

+
+* Fixed #1192. "TypeError: bad operand type for unary" in some cases when
+  installing wheels using --find-links (Pull #1218).
+
+* Fixed #1133 and #317. Archive contents are now written based on system
+  defaults and umask (i.e. permissions are not preserved), except that regular
+  files with any execute permissions have the equivalent of "chmod +x" applied
+  after being written (Pull #1146).
+
+* PreviousBuildDirError now returns a non-zero exit code and prevents the
+  previous build dir from being cleaned in all cases (Pull #1162).

+**1.4 (2013-07-23)**
+
+
+* **BACKWARD INCOMPATIBLE** pip now only installs stable versions by default,
+  and offers a new ``--pre`` option to also find pre-release and development
+  versions. (Pull #834)
+
+* **BACKWARD INCOMPATIBLE** Dropped support for Python 2.5. The minimum

+
+* pip will now warn when installing a file that is either hosted externally to

+  --allow-insecure NAME respectively. (Pull #985)
+
+* If an already-downloaded or cached file has a bad hash, re-download it rather

+
+* Fixed issue #32 - pip fails when server does not send content-type header.
+  Thanks Hugo Lopes Tavares and Kelsey Hightower (Pull #872).
+
+* "Vendorized" distlib as pip.vendor.distlib (https://distlib.readthedocs.org/).

+* Fixed git VCS backend with git 1.8.3. (Pull #967)
+
+
+**1.3.1 (2013-03-08)**

+* Split help output into general vs command-specific option groups.
+  Thanks Georgi Valkov. (Pull #744; Pull #721 contains preceding refactor)
+
+* Fixed dependency resolution when installing from archives with uppercase
+  project names. (Pull #724)
+
+* Fixed problem where re-installs always occurred when using file:// find-links.
+  (Pulls #683/#702)
+
+* "pip install -v" now shows the full download url, not just the archive name.
+  Thanks Marc Abramowitz (Pull #687)
+
+* Fix to prevent unnecessary PyPI redirects. Thanks Alex Gronholm (Pull #695)
+
+* Fixed issue #670 - install failure under Python 3 when the same version

+
+* Explicitly ignore rel='download' links while looking for html pages.

+  Thanks Przemek Wrzos.  (Issue #253 / Pull #693)
+
+
+**1.2.1 (2012-09-06)**
+
+

+  the fix, Marcus Smith.
+
+
+**1.2 (2012-09-01)**
+

+  to ``pip install gmpy``; sdist filename must begin with full project name
+  followed by a dash. Thanks casevh for the report.
+
+* Fixed issue #504 - allow package URLS to have querystrings. Thanks W.
+  Trevor King.
+
+* Fixed issue #58 - pip freeze now falls back to non-editable format rather
+  than blowing up if it can't determine the origin repository of an editable.
+  Thanks Rory McCann.
+
+* Added a `__main__.py` file to enable `python -m pip` on Python versions
+  that support it. Thanks Alexey Luchko.
+
+* Fixed issue #487 - upgrade from VCS url of project that does exist on
+  index. Thanks Andrew Knapp for the report.
+
+* Fixed issue #486 - fix upgrade from VCS url of project with no distribution
+  on index.  Thanks Andrew Knapp for the report.
+
+* Fixed issue #427 - clearer error message on a malformed VCS url. Thanks
+  Thomas Fenzl.
+

+
+* Moved tests to be run on Travis CI: http://travis-ci.org/pypa/pip
+
+* Added a better help formatter.
+
+
+**1.1 (2012-02-16)**
+

+  then fails. Thanks Marc Abramowitz.
+
+* Added ``--target`` option for installing directly to arbitrary directory.
+  Thanks Stavros Korokithakis.
+

+  Thanks Qiangning Hong.
+
+* Errors from subprocesses will display the current working directory.
+  Thanks Antti Kaihola.
+
+* Fixed issue #369 - compatibility with Subversion 1.7. Thanks Qiangning
+  Hong. Note that setuptools remains incompatible with Subversion 1.7; to
+  get the benefits of pip's support you must use Distribute rather than
+  setuptools.
+
+* Fixed issue #57 - ignore py2app-generated OS X mpkg zip files in finder.
+  Thanks Rene Dudfield.
+
+* Fixed issue #182 - log to ~/Library/Logs/ by default on OS X framework
+  installs. Thanks Dan Callahan for report and patch.
+
+* Fixed issue #310 - understand version tags without minor version ("py3")
+  in sdist filenames. Thanks Stuart Andrews for report and Olivier Girardot for
+  patch.

+  --index-url or --find-links. Thanks Herbert Pfennig.
+
+* Fixed issue #288 - handle symlinks properly. Thanks lebedov for the patch.
+

+  packages. Thanks iguananaut for the pull request.
+
+* Removed ``-E``/``--environment`` option and ``PIP_RESPECT_VIRTUALENV``;
+  both use a restart-in-venv mechanism that's broken, and neither one is
+  useful since every virtualenv now has pip inside it.  Replace ``pip -E
+  path/to/venv install Foo`` with ``virtualenv path/to/venv &&
+  path/to/venv/pip install Foo``.
+
+* Fixed issue #366 - pip throws IndexError when it calls `scraped_rel_links`
+
+* Fixed issue #22 - pip search should set and return a userful shell status code
+
+* Fixed issue #351 and #365 - added global ``--exists-action`` command line
+  option to easier script file exists conflicts, e.g. from editable
+  requirements from VCS that have a changed repo URL.

+  Thanks Alex Morega.
+
+* Fixed uninstall of packages from system Python for users of Debian/Ubuntu
+  python-setuptools package (workaround until fixed in Debian and Ubuntu).
+
+* Added `get-pip.py <https://raw.github.com/pypa/pip/master/contrib/get-pip.py>`_
+  installer. Simply download and execute it, using the Python interpreter of
+  your choice::

+
+    pip install git+https://github.com/pypa/pip/
+
+* Fixed issue #175 - Correctly locate build and source directory on Mac OS X.
+
+* Added ``git+https://`` scheme to Git VCS backend.
+
+
+**0.8.1**

+  Ronny Pfannschmidt.
+
+* Added support for `PyPI mirrors <http://pypi.python.org/mirrors>`_ as
+  defined in `PEP 381 <http://www.python.org/dev/peps/pep-0381/>`_, from
+  Jannis Leidel.

+
+* Fixed issue #107 - Can't install if a directory in cwd has the same name as the package you're installing.
+
+* Fixed issue #39 - --install-option="--prefix=~/.local" ignored with -e.
+  Thanks Ronny Pfannschmidt and Wil Tan.
+
+
+**0.8**
+
+
+* Track which ``build/`` directories pip creates, never remove directories
+  it doesn't create.  From Hugo Lopes Tavares.
+
+* Pip now accepts file:// index URLs. Thanks Dave Abrahams.
+
+* Various cleanup to make test-running more consistent and less fragile.
+  Thanks Dave Abrahams.
+
+* Real Windows support (with passing tests). Thanks Dave Abrahams.
+
+* ``pip-2.7`` etc. scripts are created (Python-version specific scripts)
+
+* ``contrib/build-standalone`` script creates a runnable ``.zip`` form of
+  pip, from Jannis Leidel
+
+* Editable git repos are updated when reinstalled
+
+* Fix problem with ``--editable`` when multiple ``.egg-info/`` directories
+  are found.
+
+* A number of VCS-related fixes for ``pip freeze``, from Hugo Lopes Tavares.
+
+* Significant test framework changes, from Hugo Lopes Tavares.
+
+
+**0.7.2**
+
+
+* Set zip_safe=False to avoid problems some people are encountering where
+  pip is installed as a zip file.
+
+
+**0.7.1**
+
+
+* Fixed opening of logfile with no directory name. Thanks Alexandre Conrad.
+

+
+
+**0.7**
+
+
+* Fixed uninstallation on Windows
+* Added ``pip search`` command.
+* Tab-complete names of installed distributions for ``pip uninstall``.
+* Support tab-completion when there is a global-option before the
+  subcommand.
+* Install header files in standard (scheme-default) location when installing
+  outside a virtualenv. Install them to a slightly more consistent
+  non-standard location inside a virtualenv (since the standard location is
+  a non-writable symlink to the global location).
+* pip now logs to a central location by default (instead of creating
+  ``pip-log.txt`` all over the place) and constantly overwrites the
+  file in question. On Unix and Mac OS X this is ``'$HOME/.pip/pip.log'``
+  and on Windows it's ``'%HOME%\\pip\\pip.log'``. You are still able to
+  override this location with the ``$PIP_LOG_FILE`` environment variable.
+  For a complete (appended) logfile use the separate ``'--log'`` command line
+  option.
+* Fixed an issue with Git that left an editable packge as a checkout of a
+  remote branch, even if the default behaviour would have been fine, too.

+* Don't print unwanted debug information when running the freeze command.
+* Create log file directory automatically. Thanks Alexandre Conrad.
+* Make test suite easier to run successfully. Thanks Dave Abrahams.
+* Fixed "pip install ." and "pip install .."; better error for directory
+  without setup.py. Thanks Alexandre Conrad.
+* Support Debian/Ubuntu "dist-packages" in zip command. Thanks duckx.
+* Fix relative --src folder. Thanks Simon Cross.
+* Handle missing VCS with an error message. Thanks Alexandre Conrad.
+* Added --no-download option to install; pairs with --no-install to separate
+  download and installation into two steps. Thanks Simon Cross.
+* Fix uninstalling from requirements file containing -f, -i, or
+  --extra-index-url.
+* Leftover build directories are now removed. Thanks Alexandre Conrad.
+
+
+**0.6.3**
+
+

+  copied into the bundle), from Whit Morriss.
+
+
+**0.6**
+
+
+* Add ``pip uninstall`` and uninstall-before upgrade (from Carl
+  Meyer).
+
+* Extended configurability with config files and environment variables.
+
+* Allow packages to be upgraded, e.g., ``pip install Package==0.1``
+  then ``pip install Package==0.2``.
+
+* Allow installing/upgrading to Package==dev (fix "Source version does not
+  match target version" errors).
+
+* Added command and option completion for bash and zsh.
+
+* Extended integration with virtualenv by providing an option to
+  automatically use an active virtualenv and an option to warn if no active
+  virtualenv is found.
+
+* Fixed a bug with pip install --download and editable packages, where
+  directories were being set with 0000 permissions, now defaults to 755.
+
+* Fixed uninstallation of easy_installed console_scripts.
+
+* Fixed uninstallation on Mac OS X Framework layout installs
+
+* Fixed bug preventing uninstall of editables with source outside venv.
+

+
+
+**0.5**

+
+* Added ability to override the default log file name (``pip-log.txt``)
+  with the environmental variable ``$PIP_LOG_FILE``.
+
+* Made the freeze command print installed packages to stdout instead of
+  writing them to a file. Use simple redirection (e.g.
+  ``pip freeze > stable-req.txt``) to get a file with requirements.
+
+* Fixed problem with freezing editable packages from a Git repository.
+
+* Added support for base URLs using ``<base href='...'>`` when parsing
+  HTML pages.
+
+* Fixed installing of non-editable packages from version control systems.
+
+* Fixed issue with Bazaar's bzr+ssh scheme.
+
+* Added --download-dir option to the install command to retrieve package
+  archives. If given an editable package it will create an archive of it.
+
+* Added ability to pass local file and directory paths to ``--find-links``,
+  e.g. ``--find-links=file:///path/to/my/private/archive``
+
+* Reduced the amount of console log messages when fetching a page to find a
+  distribution was problematic. The full messages can be found in pip-log.txt.
+
+* Added ``--no-deps`` option to install ignore package dependencies
+
+* Added ``--no-index`` option to ignore the package index (PyPI) temporarily
+
+* Fixed installing editable packages from Git branches.
+
+* Fixes freezing of editable packages from Mercurial repositories.
+
+* Fixed handling read-only attributes of build files, e.g. of Subversion and
+  Bazaar on Windows.
+
+* When downloading a file from a redirect, use the redirected
+  location's extension to guess the compression (happens specifically
+  when redirecting to a bitbucket.org tip.gz file).
+
+* Editable freeze URLs now always use revision hash/id rather than tip or
+  branch names which could move.
+
+* Fixed comparison of repo URLs so incidental differences such as
+  presence/absence of final slashes or quoted/unquoted special
+  characters don't trigger "ignore/switch/wipe/backup" choice.
+
+* Fixed handling of attempt to checkout editable install to a
+  non-empty, non-repo directory.
+
+
+**0.4**
+
+
+* Make ``-e`` work better with local hg repositories
+
+* Construct PyPI URLs the exact way easy_install constructs URLs (you
+  might notice this if you use a custom index that is
+  slash-sensitive).
+

+  <http://ionelmc.wordpress.com/>`_).
+
+* Fixed problem with not being able to install private git repositories.

+  bundles work.
+
+* Adds ``-s`` option to allow the access to the global site-packages if a
+  virtualenv is to be created.
+
+* Fixed support for Subversion 1.6.
+
+
+**0.3.1**
+
+
+* Improved virtualenv restart and various path/cleanup problems on win32.
+
+* Fixed a regression with installing from svn repositories (when not
+  using ``-e``).
+
+* Fixes when installing editable packages that put their source in a
+  subdirectory (like ``src/``).
+
+* Improve ``pip -h``
+
+
+**0.3**
+
+
+* Added support for editable packages created from Git, Mercurial and Bazaar
+  repositories and ability to freeze them. Refactored support for version
+  control systems.
+
+* Do not use ``sys.exit()`` from inside the code, instead use a
+  return.  This will make it easier to invoke programmatically.
+
+* Put the install record in ``Package.egg-info/installed-files.txt``
+  (previously they went in
+  ``site-packages/install-record-Package.txt``).
+
+* Fix a problem with ``pip freeze`` not including ``-e svn+`` when an
+  svn structure is peculiar.
+
+* Allow ``pip -E`` to work with a virtualenv that uses a different
+  version of Python than the parent environment.
+
+* Fixed Win32 virtualenv (``-E``) option.
+
+* Search the links passed in with ``-f`` for packages.
+
+* Detect zip files, even when the file doesn't have a ``.zip``
+  extension and it is served with the wrong Content-Type.
+
+* Installing editable from existing source now works, like ``pip
+  install -e some/path/`` will install the package in ``some/path/``.
+  Most importantly, anything that package requires will also be
+  installed by pip.
+
+* Add a ``--path`` option to ``pip un/zip``, so you can avoid zipping
+  files that are outside of where you expect.
+
+* Add ``--simulate`` option to ``pip zip``.
+
+
+**0.2.1**
+
+
+* Fixed small problem that prevented using ``pip.py`` without actually
+  installing pip.
+
+* Fixed ``--upgrade``, which would download and appear to install
+  upgraded packages, but actually just reinstall the existing package.
+
+* Fixed Windows problem with putting the install record in the right
+  place, and generating the ``pip`` script with Setuptools.
+
+* Download links that include embedded spaces or other unsafe
+  characters (those characters get %-encoded).
+
+* Fixed use of URLs in requirement files, and problems with some blank
+  lines.
+
+* Turn some tar file errors into warnings.
+
+
+**0.2**
+
+
+* Renamed to ``pip``, and to install you now do ``pip install
+  PACKAGE``
+
+* Added command ``pip zip PACKAGE`` and ``pip unzip PACKAGE``.  This
+  is particularly intended for Google App Engine to manage libraries
+  to stay under the 1000-file limit.
+
+* Some fixes to bundles, especially editable packages and when
+  creating a bundle using unnamed packages (like just an svn
+  repository without ``#egg=Package``).
+
+
+**0.1.4**
+
+
+* Added an option ``--install-option`` to pass options to pass
+  arguments to ``setup.py install``
+
+* ``.svn/`` directories are no longer included in bundles, as these
+  directories are specific to a version of svn -- if you build a
+  bundle on a system with svn 1.5, you can't use the checkout on a
+  system with svn 1.4.  Instead a file ``svn-checkout.txt`` is
+  included that notes the original location and revision, and the
+  command you can use to turn it back into an svn checkout.  (Probably
+  unpacking the bundle should, maybe optionally, recreate this
+  information -- but that is not currently implemented, and it would
+  require network access.)
+
+* Avoid ambiguities over project name case, where for instance
+  MyPackage and mypackage would be considered different packages.
+  This in particular caused problems on Macs, where ``MyPackage/`` and
+  ``mypackage/`` are the same directory.
+
+* Added support for an environmental variable
+  ``$PIP_DOWNLOAD_CACHE`` which will cache package downloads, so
+  future installations won't require large downloads.  Network access
+  is still required, but just some downloads will be avoided when
+  using this.
+
+
+**0.1.3**
+
+
+* Always use ``svn checkout`` (not ``export``) so that
+  ``tag_svn_revision`` settings give the revision of the package.
+
+* Don't update checkouts that came from ``.pybundle`` files.
+
+
+**0.1.2**
+
+
+* Improve error text when there are errors fetching HTML pages when
+  seeking packages.
+
+* Improve bundles: include empty directories, make them work with
+  editable packages.
+
+* If you use ``-E env`` and the environment ``env/`` doesn't exist, a
+  new virtual environment will be created.
+
+* Fix ``dependency_links`` for finding packages.
+
+
+**0.1.1**
+
+
+* Fixed a NameError exception when running pip outside of a
+  virtualenv environment.
+
+* Added HTTP proxy support (from Prabhu Ramachandran)
+
+* Fixed use of ``hashlib.md5`` on python2.5+ (also from Prabhu
+  Ramachandran)
+
+
+**0.1**
+
+
+* Initial release

+Pull Requests
+=============
+
+Submit Pull Requests against the `develop` branch.
+
+Provide a good description of what you're doing and why.
+
+Provide tests that cover your changes and try to run the tests locally first.
+
+Automated Testing
+=================
+
+All pull requests and merges to 'develop' branch are tested in `Travis <https://travis-ci.org/>`_
+based on our `.travis.yml file <https://github.com/pypa/pip/blob/develop/.travis.yml>`_.
+
+Usually, a link to your specific travis build appears in pull requests, but if not,
+you can find it on our `travis pull requests page <https://travis-ci.org/pypa/pip/pull_requests>`_
+
+The only way to trigger Travis to run again for a pull request, is to submit another change to the pull branch.
+
+We also have Jenkins CI that runs regularly for certain python versions on windows and centos.
+
+Running tests
+=============
+
+OS Requirements: subversion, bazaar, git, and mercurial.
+
+Python Requirements: tox or pytest, virtualenv, scripttest, and mock
+
+Ways to run the tests locally:
+
+::
+
+ $ tox -e py33           # The preferred way to run the tests, can use pyNN to
+                         # run for a particular version or leave off the -e to
+                         # run for all versions.
+ $ python setup.py test  # Using the setuptools test plugin
+ $ py.test               # Using py.test directly
+ $ tox                   # Using tox against pip's tox.ini
+
+
+Getting Involved
+================
+
+The pip project welcomes help in the following ways:
+
+- Making Pull Requests for code, tests, or docs.
+- Commenting on open issues and pull requests.
+- Helping to answer questions on the mailing list.
+
+If you want to become an official maintainer, start by helping out.
+
+Later, when you think you're ready, get in touch with one of the maintainers,
+and they will initiate a vote.
+
+Release Process
+===============
+
+This process includes virtualenv, since pip releases necessitate a virtualenv release.
+
+As an example, the instructions assume we're releasing pip-1.4, and virtualenv-1.10.
+
+1. Upgrade setuptools, if needed:
+
+ #. Upgrade setuptools in ``virtualenv/develop`` using the :ref:`Refresh virtualenv` process.
+ #. Create a pull request against ``pip/develop`` with a modified ``.travis.yml`` file that installs virtualenv from ``virtualenv/develop``, to confirm the travis builds are still passing.
+
+2. Create Release branches:
+
+ #. Create ``pip/release-1.4`` branch.
+ #. In ``pip/develop``, change ``pip.version`` to '1.5.dev1'.
+ #. Create ``virtualenv/release-1.10`` branch.
+ #. In ``virtualenv/develop``, change ``virtualenv.version`` to '1.11.dev1'.
+
+3. Prepare "rcX":
+
+ #. In ``pip/release-1.4``, change ``pip.version`` to '1.4rcX', and tag with '1.4rcX'.
+ #. Build a pip sdist from ``pip/release-1.4``, and build it into ``virtualenv/release-1.10`` using the :ref:`Refresh virtualenv` process.
+ #. In ``virtualenv/release-1.10``, change ``virtualenv.version`` to '1.10rcX', and tag with '1.10rcX'.
+
+4. Announce ``pip-1.4rcX`` and ``virtualenv-1.10rcX`` with the :ref:`RC Install Instructions` and elicit feedback.
+
+5. Apply fixes to 'rcX':
+
+ #. Apply fixes to ``pip/release-1.4`` and ``virtualenv/release-1.10``
+ #. Periodically merge fixes to ``pip/develop`` and ``virtualenv/develop``
+
+6. Repeat #4 thru #6 if needed.
+
+7. Final Release:
+
+ #. In ``pip/release-1.4``, change ``pip.version`` to '1.4', and tag with '1.4'.
+ #. Merge ``pip/release-1.4`` to ``pip/master``.
+ #. Build a pip sdist from ``pip/release-1.4``, and load it into ``virtualenv/release-1.10`` using the :ref:`Refresh virtualenv` process.
+ #. Merge ``vitualenv/release-1.10`` to ``virtualenv/develop``.
+ #. In ``virtualenv/release-1.10``, change ``virtualenv.version`` to '1.10', and tag with '1.10'.
+ #. Merge ``virtualenv/release-1.10`` to ``virtualenv/master``
+ #. Build and upload pip and virtualenv sdists to PyPI.

+"ImportError: No module named setuptools"
++++++++++++++++++++++++++++++++++++++++++
+
+Although using ``pip install --upgrade setuptools`` to upgrade from distribute
+to setuptools works in isolation, it's possible to get "ImportError: No module
+named setuptools" when using pip<1.4 to upgrade a package that depends on
+setuptools or distribute.
+
+e.g. when running a command like this:  `pip install --upgrade pyramid`
+
+Solution
+~~~~~~~~
+
+To prevent the problem in *new* environments (that aren't broken yet):
+
+* Option 1:
+
+ * *First* run `pip install -U setuptools`,
+ * *Then* run the command to upgrade your package (e.g. `pip install --upgrade pyramid`)
+
+* Option 2:
+
+ * Upgrade pip using :ref:`get-pip <get-pip>`
+ * *Then* run the command to upgrade your package (e.g. `pip install --upgrade pyramid`)
+
+To fix the problem once it's occurred, you'll need to manually install the new
+setuptools, then rerun the upgrade that failed.
+
+1. Download `ez_setup.py` (https://bitbucket.org/pypa/setuptools/downloads/ez_setup.py)
+2. Run `python ez_setup.py`
+3. Then rerun your upgrade (e.g. `pip install --upgrade pyramid`)
+
+
+Cause
+~~~~~
+
+distribute-0.7.3 is just an empty wrapper that only serves to require the new
+setuptools (setuptools>=0.7) so that it will be installed. (If you don't know
+yet, the "new setuptools" is a merge of distribute and setuptools back into one
+project).
+
+distribute-0.7.3 does its job well, when the upgrade is done in isolation.
+E.g. if you're currently on distribute-0.6.X, then running `pip install -U
+setuptools` works fine to upgrade you to setuptools>=0.7.
+
+The problem occurs when:
+
+1. you are currently using an older distribute (i.e. 0.6.X)
+2. and you try to use pip to upgrade a package that *depends* on setuptools or
+   distribute.
+
+As part of the upgrade process, pip builds an install list that ends up
+including distribute-0.7.3 and setuptools>=0.7 , but they can end up being
+separated by other dependencies in the list, so what can happen is this:
+
+1.  pip uninstalls the existing distribute
+2.  pip installs distribute-0.7.3 (which has no importable setuptools, that pip
+    *needs* internally to function)
+3.  pip moves on to install another dependency (before setuptools>=0.7) and is
+    unable to proceed without the setuptools package
+
+Note that pip v1.4 has fixes to prevent this.  distribute-0.7.3 (or
+setuptools>=0.7) by themselves cannot prevent this kind of problem.

+.. _`Installation`:
+
+Installation
+============
+
+Python & OS Support
+-------------------
+
+pip works with CPython versions 2.6, 2.7, 3.1, 3.2, 3.3, 3.4 and also pypy.
+
+pip works on Unix/Linux, OS X, and Windows.
+
+.. note::
+
+  Python 2.5 was supported through v1.3.1, and Python 2.4 was supported through v1.1.
+
+
+.. _`get-pip`:
+
+Install or Upgrade pip
+----------------------
+
+To install or upgrade pip, securely download `get-pip.py
+<https://raw.github.com/pypa/pip/master/contrib/get-pip.py>`_. [1]_
+
+Then run the following (which may require administrator access)::
+
+ $ python get-pip.py
+
+If `setuptools`_ (or `distribute`_) is not already installed, ``get-pip.py`` will
+install `setuptools`_ for you. [2]_
+
+To upgrade an existing `setuptools`_ (or `distribute`_), run ``pip install -U setuptools`` [3]_
+
+
+Using Package Managers
+----------------------
+
+On Linux, pip will generally be available for the system install of python using
+the system package manager, although often the latest version will be
+unavailable.
+
+On Debian and Ubuntu::
+
+   $ sudo apt-get install python-pip
+
+On Fedora::
+
+   $ sudo yum install python-pip
+
+
+.. [1] "Secure" in this context means using a modern browser or a
+       tool like `curl` that verifies SSL certificates when downloading from
+       https URLs.
+
+.. [2] Beginning with pip v1.5.1, ``get-pip.py`` stopped requiring setuptools to
+       be installed first.
+
+.. [3] Although using ``pip install --upgrade setuptools`` to upgrade from
+       distribute to setuptools works in isolation, it's possible to get
+       "ImportError: No module named setuptools" when using pip<1.4 to upgrade a
+       package that depends on setuptools or distribute. See :doc:`here for
+       details <distribute_setuptools>`.

+
+Logging
+=======
+
+Console logging
+~~~~~~~~~~~~~~~
+
+pip offers :ref:`-v, --verbose <--verbose>` and :ref:`-q, --quiet <--quiet>`
+to control the console log level.  Each option can be used multiple times and
+used together. One ``-v`` increases the verbosity by one, whereas one ``-q`` decreases it by
+one.
+
+The series of log levels, in order, are as follows::
+
+  VERBOSE_DEBUG, DEBUG, INFO, NOTIFY, WARN, ERROR, FATAL
+
+``NOTIFY`` is the default level.
+
+A few examples on how the parameters work to affect the level:
+
+* specifying nothing results in ``NOTIFY``
+* ``-v`` results in ``INFO``
+* ``-vv`` results in ``DEBUG``
+* ``-q`` results in ``WARN``
+* ``-vq`` results in ``NOTIFY``
+
+The most practical use case for users is either ``-v`` or ``-vv`` to see
+additional logging to help troubleshoot an issue.
+
+
+.. _`FileLogging`:
+
+File logging
+~~~~~~~~~~~~
+
+pip offers the :ref:`--log <--log>` option for specifying a file where a maximum
+verbosity log will be kept.  This option is empty by default. This log appends
+to previous logging.
+
+Additionally, when commands fail (i.e. return a non-zero exit code), pip writes
+a "failure log" for the failed command. This log overwrites previous
+logging. The default location is as follows:
+
+* On Unix and Mac OS X: :file:`$HOME/.pip/pip.log`
+* On Windows, the configuration file is: :file:`%HOME%\\pip\\pip.log`
+
+The option for the failure log, is :ref:`--log-file <--log-file>`.
+
+Both logs add a line per execution to specify the date and what pip executable wrote the log.
+
+Like all pip options, ``--log`` and ``log-file``, can also be set as an environment
+variable, or placed into the pip config file.  See the :ref:`Configuration`
+section.

+
+Requirements File Format
+++++++++++++++++++++++++
+
+Each line of the requirements file indicates something to be installed,
+and like arguments to :ref:`pip install`, the following forms are supported::
+
+    <requirement specifier>
+    <archive url/path>
+    [-e] <local project path>
+    [-e] <vcs project url>
+
+See the :ref:`pip install Examples<pip install Examples>` for examples of all these forms.
+
+A line beginning with ``#`` is treated as a comment and ignored.
+
+Additionally, the following Package Index Options are supported:
+
+  *  :ref:`-i, --index-url <--index-url>`
+  *  :ref:`--extra-index-url <--extra-index-url>`
+  *  :ref:`--no-index <--no-index>`
+  *  :ref:`-f, --find-links <--find-links>`
+  *  :ref:`--allow-external <--allow-external>`
+  *  :ref:`--allow-all-external <--allow-external>`
+  *  :ref:`--allow-unverified <--allow-unverified>`
+
+For example, to specify :ref:`--no-index <--no-index>` and 2 :ref:`--find-links <--find-links>` locations:
+
+::
+
+--no-index
+--find-links /my/local/archives
+--find-links http://some.archives.com/archives
+
+
+Lastly, if you wish, you can refer to other requirements files, like this::
+
+    -r more_requirements.txt
+
+.. _`Requirement Specifiers`:
+
+Requirement Specifiers
+++++++++++++++++++++++
+
+pip supports installing from "requirement specifiers" as implemented in
+`pkg_resources Requirements <http://packages.python.org/setuptools/pkg_resources.html#requirement-objects>`_
+
+Some Examples:
+
+ ::
+
+  'FooProject >= 1.2'
+  Fizzy [foo, bar]
+  'PickyThing<1.6,>1.9,!=1.9.6,<2.0a0,==2.4c1'
+  SomethingWhoseVersionIDontCareAbout
+
+.. note::
+
+  Use single or double quotes around specifiers to avoid ``>`` and ``<`` being
+  interpreted as shell redirects. e.g. ``pip install 'FooProject>=1.2'``.
+
+
+
+
+.. _`Pre Release Versions`:
+
+Pre-release Versions
+++++++++++++++++++++
+
+Starting with v1.4, pip will only install stable versions as specified by
+`PEP426`_ by default. If a version cannot be parsed as a compliant `PEP426`_
+version then it is assumed to be a pre-release.
+
+If a Requirement specifier includes a pre-release or development version
+(e.g. ``>=0.0.dev0``) then pip will allow pre-release and development versions
+for that requirement. This does not include the != flag.
+
+The ``pip install`` command also supports a :ref:`--pre <install_--pre>` flag
+that will enable installing pre-releases and development releases.
+
+
+.. _PEP426: http://www.python.org/dev/peps/pep-0426
+
+.. _`Externally Hosted Files`:
+
+Externally Hosted Files
++++++++++++++++++++++++
+
+Starting with v1.4, pip will warn about installing any file that does not come
+from the primary index. As of version 1.5, pip defaults to ignoring these files
+unless asked to consider them.
+
+The ``pip install`` command supports a
+:ref:`--allow-external PROJECT <--allow-external>` option that will enable
+installing links that are linked directly from the simple index but to an
+external host that also have a supported hash fragment. Externally hosted
+files for all projects may be enabled using the
+:ref:`--allow-all-external <--allow-all-external>` flag to the ``pip install``
+command.
+
+The ``pip install`` command also supports a
+:ref:`--allow-unverified PROJECT <--allow-unverified>` option that will enable
+installing insecurely linked files. These are either directly linked (as above)
+files without a hash, or files that are linked from either the home page or the
+download url of a package.
+
+These options can be used in a requirements file.  Assuming some fictional
+`ExternalPackage` that is hosted external and unverified, then your requirements
+file would be like so::
+
+    --allow-external ExternalPackage
+    --allow-unverified ExternalPackage
+    ExternalPackage
+
+
+.. _`VCS Support`:
+
+VCS Support
++++++++++++
+
+pip supports installing from Git, Mercurial, Subversion and Bazaar, and detects
+the type of VCS using url prefixes: "git+", "hg+", "bzr+", "svn+".
+
+pip requires a working VCS command on your path: git, hg, svn, or bzr.
+
+VCS projects can be installed in :ref:`editable mode <editable-installs>` (using
+the :ref:`--editable <install_--editable>` option) or not.
+
+* For editable installs, the clone location by default is "<venv
+  path>/src/SomeProject" in virtual environments, and "<cwd>/src/SomeProject"
+  for global installs.  The :ref:`--src <install_--src>` option can be used to
+  modify this location.
+* For non-editable installs, the project is built locally in a temp dir and then
+  installed normally.
+
+The url suffix "egg=<project name>" is used by pip in it's dependency logic to
+identify the project prior to pip downloading and analyzing the metadata.
+
+Git
+~~~
+
+pip currently supports cloning over ``git``, ``git+https`` and ``git+ssh``:
+
+Here are the supported forms::
+
+    [-e] git+git://git.myproject.org/MyProject#egg=MyProject
+    [-e] git+https://git.myproject.org/MyProject#egg=MyProject
+    [-e] git+ssh://git.myproject.org/MyProject#egg=MyProject
+    -e git+git@git.myproject.org:MyProject#egg=MyProject
+
+Passing branch names, a commit hash or a tag name is possible like so::
+
+    [-e] git://git.myproject.org/MyProject.git@master#egg=MyProject
+    [-e] git://git.myproject.org/MyProject.git@v1.0#egg=MyProject
+    [-e] git://git.myproject.org/MyProject.git@da39a3ee5e6b4b0d3255bfef95601890afd80709#egg=MyProject
+
+Mercurial
+~~~~~~~~~
+
+The supported schemes are: ``hg+http``, ``hg+https``,
+``hg+static-http`` and ``hg+ssh``.
+
+Here are the supported forms::
+
+    [-e] hg+http://hg.myproject.org/MyProject#egg=MyProject
+    [-e] hg+https://hg.myproject.org/MyProject#egg=MyProject
+    [-e] hg+ssh://hg.myproject.org/MyProject#egg=MyProject
+
+You can also specify a revision number, a revision hash, a tag name or a local
+branch name like so::
+
+    [-e] hg+http://hg.myproject.org/MyProject@da39a3ee5e6b#egg=MyProject
+    [-e] hg+http://hg.myproject.org/MyProject@2019#egg=MyProject
+    [-e] hg+http://hg.myproject.org/MyProject@v1.0#egg=MyProject
+    [-e] hg+http://hg.myproject.org/MyProject@special_feature#egg=MyProject
+
+Subversion
+~~~~~~~~~~
+
+pip supports the URL schemes ``svn``, ``svn+svn``, ``svn+http``, ``svn+https``, ``svn+ssh``.
+
+You can also give specific revisions to an SVN URL, like so::
+
+    [-e] svn+svn://svn.myproject.org/svn/MyProject#egg=MyProject
+    [-e] svn+http://svn.myproject.org/svn/MyProject/trunk@2019#egg=MyProject
+
+which will check out revision 2019.  ``@{20080101}`` would also check
+out the revision from 2008-01-01. You can only check out specific
+revisions using ``-e svn+...``.
+
+Bazaar
+~~~~~~
+
+pip supports Bazaar using the ``bzr+http``, ``bzr+https``, ``bzr+ssh``,
+``bzr+sftp``, ``bzr+ftp`` and ``bzr+lp`` schemes.
+
+Here are the supported forms::
+
+    [-e] bzr+http://bzr.myproject.org/MyProject/trunk#egg=MyProject
+    [-e] bzr+sftp://user@myproject.org/MyProject/trunk#egg=MyProject
+    [-e] bzr+ssh://user@myproject.org/MyProject/trunk#egg=MyProject
+    [-e] bzr+ftp://user@myproject.org/MyProject/trunk#egg=MyProject
+    [-e] bzr+lp:MyProject#egg=MyProject
+
+Tags or revisions can be installed like so::
+
+    [-e] bzr+https://bzr.myproject.org/MyProject/trunk@2019#egg=MyProject
+    [-e] bzr+http://bzr.myproject.org/MyProject/trunk@v1.0#egg=MyProject
+
+
+Finding Packages
+++++++++++++++++
+
+pip searches for packages on `PyPI`_ using the
+`http simple interface <http://pypi.python.org/simple>`_,
+which is documented `here <http://packages.python.org/setuptools/easy_install.html#package-index-api>`_
+and `there <http://www.python.org/dev/peps/pep-0301/>`_
+
+pip offers a number of Package Index Options for modifying how packages are found.
+
+See the :ref:`pip install Examples<pip install Examples>`.
+
+
+.. _`SSL Certificate Verification`:
+
+SSL Certificate Verification
+++++++++++++++++++++++++++++
+
+Starting with v1.3, pip provides SSL certificate verification over https, for the purpose
+of providing secure, certified downloads from PyPI.
+
+
+Hash Verification
++++++++++++++++++
+
+PyPI provides md5 hashes in the hash fragment of package download urls.
+
+pip supports checking this, as well as any of the
+guaranteed hashlib algorithms (sha1, sha224, sha384, sha256, sha512, md5).
+
+The hash fragment is case sensitive (i.e. sha1 not SHA1).
+
+This check is only intended to provide basic download corruption protection.
+It is not intended to provide security against tampering. For that,
+see :ref:`SSL Certificate Verification`
+
+
+Download Cache
+++++++++++++++
+
+pip offers a :ref:`--download-cache <install_--download-cache>` option for
+installs to prevent redundant downloads of archives from PyPI.
+
+The point of this cache is *not* to circumvent the index crawling process, but
+to *just* prevent redundant downloads.
+
+Items are stored in this cache based on the url the archive was found at, not
+simply the archive name.
+
+If you want a fast/local install solution that circumvents crawling PyPI, see
+the :ref:`Fast & Local Installs`.
+
+Like all options, :ref:`--download-cache <install_--download-cache>`, can also
+be set as an environment variable, or placed into the pip config file.  See the
+:ref:`Configuration` section.
+
+
+.. _`editable-installs`:
+
+"Editable" Installs
++++++++++++++++++++
+
+"Editable" installs are fundamentally `"setuptools develop mode"
+<http://packages.python.org/setuptools/setuptools.html#development-mode>`_
+installs.
+
+You can install local projects or VCS projects in "editable" mode::
+
+$ pip install -e path/to/SomeProject
+$ pip install -e git+http://repo/my_project.git#egg=SomeProject
+
+For local projects, the "SomeProject.egg-info" directory is created relative to
+the project path.  This is one advantage over just using ``setup.py develop``,
+which creates the "egg-info" directly relative the current working directory.
+
+
+
+Controlling setup_requires
+++++++++++++++++++++++++++
+
+Setuptools offers the ``setup_requires`` `setup() keyword
+<http://pythonhosted.org/setuptools/setuptools.html#new-and-changed-setup-keywords>`_
+for specifying dependencies that need to be present in order for the `setup.py`
+script to run.  Internally, Setuptools uses ``easy_install`` to fulfill these
+dependencies.
+
+pip has no way to control how these dependencies are located.  None of the
+Package Index Options have an effect.
+
+The solution is to configure a "system" or "personal" `Distutils configuration
+file
+<http://docs.python.org/2/install/index.html#distutils-configuration-files>`_ to
+manage the fulfillment.
+
+For example, to have the dependency located at an alternate index, add this:
+
+::
+
+  [easy_install]
+  index_url = https://my.index-mirror.com
+
+To have the dependency located from a local directory and not crawl PyPI, add this:
+
+::
+
+  [easy_install]
+  allow_hosts = ''
+  find_links = file:///path/to/local/archives

+
+Installing Packages
+*******************
+
+pip supports installing from `PyPI`_, version control, local projects, and
+directly from distribution files.
+
+
+The most common scenario is to install from `PyPI`_ using :ref:`Requirement
+Specifiers`
+
+  ::
+
+  $ pip install SomePackage            # latest version
+  $ pip install SomePackage==1.0.4     # specific version
+  $ pip install 'SomePackage>=1.0.4'     # minimum version
+
+
+For more information and examples, see the :ref:`pip install` reference.
+
+
+.. _`Requirements Files`:
+
+Requirements Files
+******************
+
+"Requirements files" are files containing a list of items to be
+installed using :ref:`pip install` like so:
+
+ ::
+
+   pip install -r requirements.txt
+
+
+Details on the format of the files are here: :ref:`Requirements File Format`.
+
+Logically, a Requirements file is just a list of :ref:`pip install` arguments
+placed in a file.
+
+In practice, there are 4 common uses of Requirements files:
+
+1. Requirements files are used to hold the result from :ref:`pip freeze` for the
+   purpose of achieving :ref:`repeatable installations <Repeatability>`.  In
+   this case, your requirement file contains a pinned version of everything that
+   was installed when `pip freeze` was run.
+
+   ::
+
+     pip freeze > requirements.txt
+     pip install -r requirements.txt
+
+2. Requirements files are used to force pip to properly resolve dependencies.
+   As it is now, pip `doesn't have true dependency resolution
+   <https://github.com/pypa/pip/issues/988>`_, but instead simply uses the first
+   specification it finds for a project. E.g if `pkg1` requires `pkg3>=1.0` and
+   `pkg2` requires `pkg3>=1.0,<=2.0`, and if `pkg1` is resolved first, pip will
+   only use `pkg3>=1.0`, and could easily end up installing a version of `pkg3`
+   that conflicts with the needs of `pkg2`.  To solve this problem, you can
+   place `pkg3>=1.0,<=2.0` (i.e. the correct specification) into your
+   requirements file directly along with the other top level requirements. Like
+   so:
+
+   ::
+
+     pkg1
+     pkg2
+     pkg3>=1.0,<=2.0
+
+
+3. Requirements files are used to force pip to install an alternate version of a
+   sub-dependency.  For example, suppose `ProjectA` in your requirements file
+   requires `ProjectB`, but the latest version (v1.3) has a bug, you can force
+   pip to accept earlier versions like so:

+
+     ProjectA
+     ProjectB<1.3
+
+4. Requirements files are used to override a dependency with a local patch that
+   lives in version control.  For example, suppose a dependency,
+   `SomeDependency` from PyPI has a bug, and you can't wait for an upstream fix.
+   You could clone/copy the src, make the fix, and place it in vcs with the tag
+   `sometag`.  You'd reference it in your requirements file with a line like so:
+
+   ::
+
+     git+https://myvcs.com/some_dependency@sometag#egg=SomeDependency
+
+   If `SomeDependency` was previously a top-level requirement in your
+   requirements file, then **replace** that line with the new line. If
+   `SomeDependency` is a sub-dependency, then **add** the new line.
+
+
+It's important to be clear that pip determines package dependencies using
+`install_requires metadata
+<http://pythonhosted.org/setuptools/setuptools.html#declaring-dependencies>`_,
+not by discovering `requirements.txt` files embedded in projects.

+
+.. _`Installing from Wheels`:
+
+Installing from Wheels
+**********************
+
+"Wheel" is a built, archive format that can greatly speed installation compared
+to building and installing from source archives. For more information, see the
+`Wheel docs <http://wheel.readthedocs.org>`_ ,
+`PEP427 <http://www.python.org/dev/peps/pep-0427>`_, and
+`PEP425 <http://www.python.org/dev/peps/pep-0425>`_
+
+Pip prefers Wheels where they are available. To disable this, use the
+:ref:`--no-use-wheel <install_--no-use-wheel>` flag for :ref:`pip install`.
+
+If no satisfactory wheels are found, pip will default to finding source archives.
+
+
+To install directly from a wheel archive:
+
+::
+
+ pip install SomePackage-1.0-py2.py3-none-any.whl
+
+
+For the cases where wheels are not available, pip offers :ref:`pip wheel` as a
+convenience, to build wheels for all your requirements and dependencies.
+
+:ref:`pip wheel` requires the `wheel package
+<https://pypi.python.org/pypi/wheel>`_ to be installed, which provides the
+"bdist_wheel" setuptools extension that it uses.
+
+To build wheels for your requirements and all their dependencies to a local directory:
+
+::
+
+ pip install wheel
+ pip wheel --wheel-dir=/local/wheels -r requirements.txt
+
+
+And *then* to install those requirements just using your local directory of wheels (and not from PyPI):
+
+::
+
+ pip install --no-index --find-links=/local/wheels -r requirements.txt
+
+
+Uninstalling Packages
+*********************
+
+pip is able to uninstall most packages like so:
+
+::
+
+ $ pip uninstall SomePackage
+
+pip also performs an automatic uninstall of an old version of a package
+before upgrading to a newer version.
+
+For more information and examples, see the :ref:`pip uninstall` reference.
+
+
+Listing Packages
+****************
+
+To list installed packages:
+
+::
+
+  $ pip list
+  Pygments (1.5)
+  docutils (0.9.1)
+  Sphinx (1.1.2)
+  Jinja2 (2.6)
+
+To list outdated packages, and show the latest version available:
+
+::
+
+  $ pip list --outdated
+  docutils (Current: 0.9.1 Latest: 0.10)
+  Sphinx (Current: 1.1.2 Latest: 1.1.3)
+
+
+To show details about an installed package:
+
+::
+
+  $ pip show sphinx
+  ---
+  Name: Sphinx
+  Version: 1.1.3
+  Location: /my/env/lib/pythonx.x/site-packages
+  Requires: Pygments, Jinja2, docutils
+
+
+For more information and examples, see the :ref:`pip list` and :ref:`pip show`
+reference pages.
+
+
+Searching for Packages
+**********************
+
+pip can search `PyPI`_ for packages using the ``pip search``
+command::
+
+    $ pip search "query"
+
+The query will be used to search the names and summaries of all
+packages.
+
+For more information and examples, see the :ref:`pip search` reference.
+
+.. _`Configuration`:
+
+Configuration
+*************
+
+.. _config-file:
+
+Config file
+------------
+
+pip allows you to set all command line option defaults in a standard ini
+style config file.
+
+The names and locations of the configuration files vary slightly across
+platforms.
+
+* On Unix and Mac OS X the configuration file is: :file:`$HOME/.pip/pip.conf`
+* On Windows, the configuration file is: :file:`%HOME%\\pip\\pip.ini`
+
+You can set a custom path location for the config file using the environment variable ``PIP_CONFIG_FILE``.
+
+In a virtual environment, an additional config file will be read from the base
+directory of the virtualenv (``sys.prefix`` as reported by Python). The base
+name of the file is the same as the user configuration file (:file:`pip.conf`
+on Unix and OSX, :file:`pip.ini` on Windows). Values in the virtualenv-specific
+configuration file take precedence over those in the user's configuration file
+(whether from the user home or specified via ``PIP_CONFIG_FILE``).
+
+The names of the settings are derived from the long command line option, e.g.
+if you want to use a different package index (``--index-url``) and set the
+HTTP timeout (``--default-timeout``) to 60 seconds your config file would
+look like this:
+
+.. code-block:: ini
+
+    [global]
+    timeout = 60
+    index-url = http://download.zope.org/ppix
+
+Each subcommand can be configured optionally in its own section so that every
+global setting with the same name will be overridden; e.g. decreasing the
+``timeout`` to ``10`` seconds when running the `freeze`
+(`Freezing Requirements <./#freezing-requirements>`_) command and using
+``60`` seconds for all other commands is possible with:
+
+.. code-block:: ini
+
+    [global]
+    timeout = 60
+
+    [freeze]
+    timeout = 10
+
+
+Boolean options like ``--ignore-installed`` or ``--no-dependencies`` can be
+set like this:
+
+.. code-block:: ini
+
+    [install]
+    ignore-installed = true
+    no-dependencies = yes
+
+Appending options like ``--find-links`` can be written on multiple lines:
+
+.. code-block:: ini
+
+    [global]
+    find-links =
+        http://download.example.com
+
+    [install]
+    find-links =
+        http://mirror1.example.com
+        http://mirror2.example.com
+
+
+Environment Variables
+---------------------
+
+pip's command line options can be set with environment variables using the
+format ``PIP_<UPPER_LONG_NAME>`` . Dashes (``-``) have to be replaced with
+underscores (``_``).
+
+For example, to set the default timeout::
+
+    export PIP_DEFAULT_TIMEOUT=60
+
+This is the same as passing the option to pip directly::
+
+    pip --default-timeout=60 [...]
+
+To set options that can be set multiple times on the command line, just add
+spaces in between values. For example::
+
+    export PIP_FIND_LINKS="http://mirror1.example.com http://mirror2.example.com"
+
+is the same as calling::
+
+    pip install --find-links=http://mirror1.example.com --find-links=http://mirror2.example.com
+
+
+Config Precedence
+-----------------
+
+Command line options have precedence over environment variables, which have precedence over the config file.
+
+Within the config file, command specific sections have precedence over the global section.
+
+Examples:
+
+- ``--host=foo`` overrides ``PIP_HOST=foo``
+- ``PIP_HOST=foo`` overrides a config file with ``[global] host = foo``
+- A command specific section in the config file ``[<command>] host = bar``
+  overrides the option with same name in the ``[global]`` config file section
+
+
+Command Completion
+------------------
+
+pip comes with support for command line completion in bash and zsh.
+
+To setup for bash::
+
+    $ pip completion --bash >> ~/.profile
+
+To setup for zsh::
+
+    $ pip completion --zsh >> ~/.zprofile
+
+Alternatively, you can use the result of the ``completion`` command
+directly with the eval function of you shell, e.g. by adding the following to your startup file::
+
+    eval "`pip completion --bash`"
+
+
+
+.. _`Fast & Local Installs`:
+
+Fast & Local Installs
+*********************
+
+Often, you will want a fast install from local archives, without probing PyPI.
+
+First, download the archives that fulfill your requirements::
+
+$ pip install --download <DIR> -r requirements.txt
+
+Then, install using  :ref:`--find-links <--find-links>` and :ref:`--no-index <--no-index>`::
+
+$ pip install --no-index --find-links=[file://]<DIR> -r requirements.txt
+
+
+Non-recursive upgrades
+************************
+
+``pip install --upgrade`` is currently written to perform a recursive upgrade.
+
+E.g. supposing:
+
+* `SomePackage-1.0` requires `AnotherPackage>=1.0`
+* `SomePackage-2.0` requires `AnotherPackage>=1.0` and `OneMorePoject==1.0`
+* `SomePackage-1.0` and `AnotherPackage-1.0` are currently installed
+* `SomePackage-2.0` and `AnotherPackage-2.0` are the latest versions available on PyPI.
+
+Running ``pip install --upgrade SomePackage`` would upgrade `SomePackage` *and* `AnotherPackage`
+despite `AnotherPackage` already being satisifed.
+
+If you would like to perform a non-recursive upgrade perform these 2 steps::
+
+  pip install --upgrade --no-deps SomePackage
+  pip install SomePackage
+
+The first line will upgrade `SomePackage`, but not dependencies like `AnotherPackage`.  The 2nd line will fill in new dependencies like `OneMorePackage`.
+
+
+User Installs
+*************
+
+With Python 2.6 came the `"user scheme" for installation
+<http://docs.python.org/install/index.html#alternate-installation-the-user-scheme>`_,
+which means that all Python distributions support an alternative install
+location that is specific to a user.  The default location for each OS is
+explained in the python documentation for the `site.USER_BASE
+<http://docs.python.org/library/site.html#site.USER_BASE>`_ variable.  This mode
+of installation can be turned on by specifying the :ref:`--user
+<install_--user>` option to ``pip install``.
+
+Moreover, the "user scheme" can be customized by setting the
+``PYTHONUSERBASE`` environment variable, which updates the value of ``site.USER_BASE``.
+
+To install "SomePackage" into an environment with site.USER_BASE customized to '/myappenv', do the following::
+
+    export PYTHONUSERBASE=/myappenv
+    pip install --user SomePackage
+
+
+``pip install --user`` follows four rules:
+
+#. When globally installed packages are on the python path, and they *conflict*
+   with the installation requirements, they are ignored, and *not*
+   uninstalled.
+#. When globally installed packages are on the python path, and they *satisfy*
+   the installation requirements, pip does nothing, and reports that
+   requirement is satisfied (similar to how global packages can satisfy
+   requirements when installing packages in a ``--system-site-packages``
+   virtualenv).
+#. pip will not perform a ``--user`` install in a ``--no-site-packages``
+   virtualenv (i.e. the default kind of virtualenv), due to the user site not
+   being on the python path.  The installation would be pointless.
+#. In a ``--system-site-packages`` virtualenv, pip will not install a package
+   that conflicts with a package in the virtualenv site-packages.  The --user
+   installation would lack sys.path precedence and be pointless.
+
+
+To make the rules clearer, here are some examples:
+
+
+From within a ``--no-site-packages`` virtualenv (i.e. the default kind)::
+
+  $ pip install --user SomePackage
+  Can not perform a '--user' install. User site-packages are not visible in this virtualenv.
+
+
+From within a ``--system-site-packages`` virtualenv where ``SomePackage==0.3`` is already installed in the virtualenv::
+
+  $ pip install --user SomePackage==0.4
+  Will not install to the user site because it will lack sys.path precedence
+
+
+From within a real python, where ``SomePackage`` is *not* installed globally::
+
+  $ pip install --user SomePackage
+  [...]
+  Successfully installed SomePackage
+
+
+From within a real python, where ``SomePackage`` *is* installed globally, but is *not* the latest version::
+
+  $ pip install --user SomePackage
+  [...]
+  Requirement already satisfied (use --upgrade to upgrade)
+
+  $ pip install --user --upgrade SomePackage
+  [...]
+  Successfully installed SomePackage
+
+
+From within a real python, where ``SomePackage`` *is* installed globally, and is the latest version::
+
+  $ pip install --user SomePackage
+  [...]
+  Requirement already satisfied (use --upgrade to upgrade)
+
+  $ pip install --user --upgrade SomePackage
+  [...]
+  Requirement already up-to-date: SomePackage
+
+  # force the install
+  $ pip install --user --ignore-installed SomePackage
+  [...]
+  Successfully installed SomePackage
+
+
+.. _`Repeatability`:
+
+Ensuring Repeatability
+**********************
+
+Three things are required to fully guarantee a repeatable installation using requirements files.
+
+1. The requirements file was generated by ``pip freeze`` or you're sure it only
+   contains requirements that specify a specific version.
+
+2. The installation is performed using :ref:`--no-deps <install_--no-deps>`.
+   This guarantees that only what is explicitly listed in the requirements file is
+   installed.
+
+3. The installation is performed against an index or find-links location that is
+   guaranteed to *not* allow archives to be changed and updated without a
+   version increase.  Unfortunately, this is *not* true on PyPI. It is possible
+   for the same pypi distribution to have a different hash over time. Project
+   authors are allowed to delete a distribution, and then upload a new one with
+   the same name and version, but a different hash. See `Issue #1175
+   <https://github.com/pypa/pip/issues/1175>`_ for plans to add hash
+   confirmation to pip, or a new "lock file" notion, but for now, know that the `peep
+   project <https://pypi.python.org/pypi/peep>`_ offers this feature on top of pip
+   using requirements file comments.

+        
+        Install a package from `PyPI`_:
+        
+        ::
+        
+          $ pip install SomePackage
+            [...]

+             [...]
+        
+        List what packages are outdated:
+        
+        ::
+        
+          $ pip list --outdated
+            SomePackage (Current: 1.0 Latest: 2.0)
+        
+        Upgrade a package:
+        
+        ::
+        
+          $ pip install --upgrade SomePackage
+            [...]
+            Found existing installation: SomePackage 1.0
+            Uninstalling SomePackage:
+              Successfully uninstalled SomePackage
+            Running setup.py install for SomePackage
+            Successfully installed SomePackage
+        
+        Uninstall a package:
+        
+        ::
+        
+          $ pip uninstall SomePackage
+            Uninstalling SomePackage:
+              /my/env/lib/pythonx.x/site-packages/somepackage
+            Proceed (y/n)? y
+            Successfully uninstalled SomePackage
+
